BALL OF BINDER TWINE AND APPARATUS FOR PRODU'CING THE SAME- Application filed November 2, 1925. Serial No. 66,174.

This invention relates to improvements in balls of binder twine and apparatus for producing the same. Owing to the characteristic wiry and stiff nature of the fibers of hemp from which binder twine is made the twine has fibers projecting from it in all directions to a distance equalling the greater part of an inch and even 'more in many cases. It is the custom of some makers to wind this twine into a ball or mass in the nature of a cylindrical cop having a plane end in which the plane end is made by the characteristic of the winding machine that brings each movement of the thread guide to the plane and then backward toward the other end of the cop. These balls have advantages because of the superior density with which they can be' wound and the superior uniformity of size, dimension ano shape; but the individual fibers projecting from those threads which are exposed at the end of the cop make a forest of small hair's or fibers projecting from the end of the package. The present invention provides means by which to a great extent theseprojecting fiber ends are'turned inward and bound under the threads in the package. Thereby two eifects are gained; the end aspect of the cop is greatly improved by being given a smooth and finished appearance; and there is to some extent a binding effect of these turned-in fibers, which contribute toward holding the ends of the package in better shape by constituting a multitude of small anchors applied to the exposed portions of each thread at the end of the Wound. mass. This said anchorage serves conversely to hold those fibers in the midst of the package, instead of letting them project. The package produced by the invention is like those which have been formerly produced, except that to a great extent the fibers which in the former package have been outstanding from the end are turned in and embedded in the package; the few which may remain having for one reason or another missed the operation of the wipers hereinafter described.

The invention relates to the production of a mass with its end fibers thus turned in These are in the nature of wi ers, one be-.

ing adapted to engage the pac 'age at each end. Each wiper has an end bearing sur face and a surface reaching in a little way from the end with hearing on the cylindrical side of the mass which is in process of being wound. As applied to the ordinary machine, the attachment embodies an arm with a vertical side surface and with a horizontal finger. The vertical face engaging the end of the package tends to direct the projecting fibers in toward the body of the package when thesaid package 15 rotated; and the finger projecting inward therefrom and resting on the periphery of the package in adapted to pass over the fibers thus turned inward and retain them upon the body of the package until the same are permanently secured by the next succeeding thread being wound thereupon, which thread is laid in close proximity. In this manner the package When complete is rid of the vast amount of projecting fibers at its ends, there being but comparatively few which escape the binding operation; and the general appearance of the package is greatly improved. And the ends of the package are to a degree strengthened by the tendency of .the inturned fibers to anchor the exposed end portions of the threads to prevent slippage of those loop parts of the thread whose yielding produces looseness and permits collapse of the mass or even is liable to cause it. 4

One form of the invention is illustrated in the accompanying drawings. It is intended that the patent shall cover by suitable expression in the appended claims whatever features of patentable novelty exist in the invention disclosed.

Tn the accompanying drawings: Figure 1 is a side elevation of what is con'unonly known as a universal wound package, showing the invention applied; Figure 2 is an end view of the same; Figure 3 is an elevation in section through adetail of the device of the invention, illust-rating the position of the same upon a package; I

Figure 4 is a perspective view illustrating the approach of the wiper to projecting fibers;

Figure 5 is a similar view illustrating the manner in which the vertical face of the wiper engages fibers, directing them in.

ward; and 1 Figure 6 is a similar view illustratlng the manner in which the horizontal finger engages the inward turned fibers, holding wound package of binder twine, between I whose ends 12 12 travels the, reciprocating guide 14 for positioni'ngthestrand upon the package as it is wound. Arms 16, supported from the frame of the winding machine, are positioned'at the ends of the package with the flat face of each lying in a vertical plane at the end of the package near the peri hery thereof, so that fibers projecting en wise from the mass beyond that plane are turned back inward. Each arm 16 also carries an inward extending finger 18 which lies horizontally upon the periphery of the package, each said finger being substantially flat. Both of these rest lightly against. or'close to their respective surfaces of' the mass, no great pressure being requisite. As the mass is rotated in the winding operation the projecting fibers 20 at the end of the package encounter the faces 16 which turn them inward as illustrated in Figure 5 of the drawings; and as the package turns further in its rotating motion the said inward turned fibers pass under the horizontal fingers 18 as shownin'Figure 6, which bend them down to positions close to the cylindrical surface. While the fibers are thus held in position by the fingers 18 the thread 22 is laid over them close to their root ends. They arethus securely held upon the body of the package and with the laying of later threads will be hidden from view. Fibers so bound within the body of the holding them there inthe path of twine which is being wound, thus causing the said fibers to be bound within the body of the mass.

2. Means for directing the endwise projecting fibers, during the winding of a mass of binder twine, comprising an element set close against the end of the package at the periphery thereof and. adapted to bend the endwise projecting fibers backward over the cylindrical surface whereon the winding is proceeding; and a finger overlying said cylindrical surface for holding the said bent fibers close to the cylindrical surface of the mass until bound thereon by the thread which is being laid in the said winding operation. y

3. An improved package of binder twine in which those fibers which tend to protrude from the ends of the wound cylindrical mass are bent over and bound between adjacent layers of the cylindrical mass.
